COMBINED VEHICLE BRAKING AND STARTING DEVICE.

Specification of Letters Patent.

Patented June 5, 1906.

Application filed September 12, 1905. Serial No. 278,174.

To all whom it may concern.-

Be it known that I, J OSEPH DE MAZARAKI, a subject of the Russian Emperor, residing at Etterbeek, near Brussels, Belgium, have in vented new and useful Improvements in and Relating to a Combined Vehicle Braking and Starting Device; and I do hereby declare the following to be a full, clear, and exact description of the same.

My present invention relates to vehicle braking and starting devices, the object being to provide a combined braking and starting device for motor-cars and the like wherein the power annihilated by the braking action when the car is stopped is accumulated by means of a particularlyarranged metal spring and utilized subsequently for starting the motor of the car, thus avoiding the use of the ordinary crank-handle for starting the motor.

In the accompanying drawings I have shown the preferred form of embodiment of my invention.

Figure 1 is a diagrammatical side elevation of a car-wheel connected with my improved braking and starting device, and Fig. 2 is a vertical cross-section through the spring-casing of the device. Fig. 3 is a top plan view of the frame of a vehicle provided with my improved braking and starting device.

Referring to the drawings, 1 indicates the usual brake-lever, adapted to be held in any desired position on the toothed segment 2 and pivoted near its lower end on a stationary pin '3. The forked lower end 5 of said lever carries a screw-threaded non-rotatable shaft 4, and arranged on the latter is a rotatable spring-case 6, around which passes an endless brake-band 7, passing also around a pulley 8, keyed on the axle of the wheel 9 to be braked. Arranged within the rotatable case 6 is a strong spiral spring 10, one end of which is attached to the shaft 4, while the other end thereof is attached to the wall of the case 6, so that said spiral spring will be wound up when said case is rotated, as hereinafter described.

The case 6 carries on one side a ratchetwheel 11, made one therewith and cooperating with a pawl 12, pivoted on the forked end of the brake-lever 1. Said pawl is disengaged from the ratchet-wheel 11 by a stationary stop 13 when the brakelever is moved forwardly in the direction of the ar row 20, Fig. 1. On the opposite side the case 6 carries a toothed wheel 14, adapted to mesh with a toothed pinion 15, keyed on an intermediate shaft 16, connected in any suitable way with the motor-shaft a of the vehicle. This connection may be made by means of a gear-wheel 21 on the shaft 16 and meshing with a gear-wheel 22 on a shaft 23, arranged at right angles with the shaft 16 and carrying a gear-wheel 24, meshing with another gearwheel 25 on said motor-shaft a, Fig. 3.

Assuming the car to be in movement and the brake-lever 1 in its intermediate position, Fig. 1, when it is desired to stop the vehicle, the carman moves the brake-lever 1 in the direction of the arrow 17, so that the brake-band 7 will be tightened, and causes the case 6 to be rotated in its screw-threaded shaft 4, whereby the inner spiral spring 10 will be wound up. At the same time the case 6 is moved laterally by the action of the screw-threads of its shaft until a projection 18 of said case strikes against an adjustable stop 19, when the spiral spring 1 0 is completely wound up and the movement of said case stopped, whereupon the brake-band 7 slides around the case 6 until the vehicle is completely stopped. This arrangement serves to prevent the spring 10 from being wound up too strongly, thus avoiding breaks thereof.

In order to start the vehicle when the motor has been stopped, the carman moves the lever 1 in the direction of the arrow 20, Fig. 1, whereby the toothed wheel 14 is caused to mesh with the pinion 15, the pawl 12 being almost simultaneously disengaged from the ratchet-wheel 11 to permit the spring 10 to be expanded and rotate the case 6 with the toothed wheel 14, which in turn actuates the pinion 15, and therefore, also, the motor-shaft for the purpose of starting the motor of the vehicle.

The stationary stop 13 is arranged so that the pawl 12 is only disengaged, when the teeth of the gear-wheels 14 and 15 are completely engaged, so that the spring 10 cannot be expanded untimely without actuating the motor-shaft.

The gear-wheel 14 is constructed and arranged so as to be connected with the case 6 when the latter is actuated by the expansion of the inner spring, while said wheel 14 is loose on said case when it is actuated by the toothed pinion 15. This occurs when the motor-shaft is rotated by the action of the motive fluid, the lever 1 being not yet brought back to its intermediate position, so that the IIO gear-wheels 14 and 15 are still in engagement. Should the wheel 14 not be loose in this case, the pinion 15 would cause the case 6 to rotate and wind up the spring 10 in opposite direction, whereby it would certainly be broken off.

My new combined braking and starting device offers great practical advantages. It avoids the use of the ordinary crank-handle, whereby the motor-shaft of a vehicle has been started heretofore. By reason of this automatic starting of the motor the carman may stop the latter each time he stops the vehicle, so as to save an appreciable quantity of fuel and avoid the prejudicial jerks and shocks produced by the movement of the motor when the vehicle is stopped.

The improved device may be readily applied to existing vehicles without appreciable changes in the ordinary construction, and it will be seen that my device acts quite independently from the will or attention of the carman.

It is manifest that my improved device is used only in combination with one wheel of the vehicle, the other wheel or wheels being braked by the usual means, suitably connected to the common brake-lever 1.

Having fully described my invention, what I claim, and desire to secure by Letters Patent, is
